MEANS roe MAKING ataivrma'ranwoon PRODUCT.

Application filed July 7,

To all-whom it may concern:

Be it known that I, HENRY J.- Gorr, a citizen of the United States, residing at Susanville, county of Lassen, State of Cali- 5 fornia, have invented certain new and useful Improvements in Means for Making a Laminated Wood Product; and I do declare the following to be a full, clear, and-exact description of same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of'this application.

This invention relates to improvements in devices for making laminated or built-up wood products, and particularly to a device for enablinga. unitary member to be ob tained from the separate parts of the prod not after being assembled.

I have particularly innlind the production of door-stiles, the exterior surfaces of which are of first-grade and relatively expensive woods of any desired kind, and a filler or body of second or third grade wood of any kind, such as the scrap blocks obtainirlfxle in quantities at'any box factory or the One of the objects of my invention is to provide a device by means of which the parts of a product of this character, are caused to be united without any dovetailing or mortising together of the body or filler memhere with each other or with the side rails being had, and such as is employed in the construction of laminated stiles heretofore.

The reason of thus dovetailing the parts as above stated, is that so far no apparatus has been devised which will successfully, and in a commercially practicable manner, enable the parts to be assembled to form a solid and unitary product without such dovetailing and the like being resorted to.

On account of this operation, laminated door stiles as at present made, even with relatively cheap and wood surfacings, are

Another object of my invention is to pro vide-a device whereby the various parts-of the stile, when assembled, are firmly comr pressed and clamped together onall sides at one operation, so that the resulting product is as strong, if not stronger, than a onepiece stile, and is also practically proof against warping. j l

clamping pparatus and mode'ozt far more expensive than a one piece stile.

tailing of the fille r blocks heret0fore thought necessary, enables me to produce a laminated stile whosecost is not only far less than present stiles of this character, but

also less than one-piecestiles. j

.These objects I accomplish parts as will fully appear by a perusal of the following specificationsand claims.

In the drawings similar characters of reference indicate corresponding parts in the several views Fig. 1 is a perspective elevation of theclamping device, with a stile assembled therein ready for clamping, and partly broken out. 7 a

Fig. 2 is an enlarged cross section of. the device, in clamping engagement with the stile.

Referring now more particularly to the characters of reference on the drawings, the stile itself comprises outer-edge rails 1- of grade A wood of the desired kind, of a suitable thickness and of the full length necessary for the completed'stile. These rails form the outer, edges of the stile. The outer side faces of the stile are formed of' continuous pieces of veneer 2 of the same kind and grade of wood as the rails 1, and

extend between the outer edges of the same, the rails fitting therebetween.

The filling or interior body of the stile is formed of longitudinally extending and transversely disposed rows of blocks 3 of any kind of wood, the blocks of each row being of the same width and height but being'of any odd-lengths available, the only requirement being that the ends of. the blocks of one rowshall be staggered with respect to the ends of the blocks of the adjacent row.

Before assembling the parts, they are first planed to the required dimensions which will form a completed product of substantially the correct dimensions. Y

In assembling, one of the veneer pieces 2 is laid flat,gl'ue is applied to the upper surface, and the edge rails 1' are placed in the properpositions thereon. The filler blocks 3 are then placed betweentherails in rows 'asabove de i with glue of course e by means of such structure and r lative arrangement of from the .clamping means, and should be placed where itmay remain 2 0r 3 days withoutb eing disturbed, before using.

I preferably use waterproof glue, and have found that the product may be immersea in water iEor considerable period without showing any tendency to warp, dis-- integrate or otherwise deteriorate.

The device I employfor applying the necessary pressure to the parts in a comineroiallypracticable and inexpensive manner is conamaeaas rene s: A rigid, an

and smooth surfaced base plate 45, of greater surface area than that of the stile with respect to the width and length of the latter, has a vertical flange or edge plate '5 projecting upwardly therefrom lor its full length, of a somewha t lesser-height than the" thickness of "the stile, and disposed somewhat close to one edge of the plate; The surface of said flange which faces the tar edge of the baseplate isperfectly straight and"sm'ooth,'and makes a 90 angle with the base. j

The "base plate supports the under veneer piece oitthestile, while the flingejli' orms an abutment and rail of-the stile.

' A ngther flat'plate 6, finished onits under face, is superimposed above the plate 4, and

has an integral full-length flange 7 depending at right angles thereof in transversely spaced relationto the flange 5 a distance not less than the width oli'the stile. Th-isfian-ge 7 "is also of lesser height the t-h-iok'ne ss of the stile. 7' j Projeoting'up from the base l-sOtl-tSlClG the plane otth flanges? are lugs 8, arranged as pairs in suitably spaced relation lengthwise of the base, The innerfaces of these lugs have on in ward slant fromtop to bottom, the slanting races project-inginto the normal a suit stiles of difierentthicknesses-H plane of location of the'fflangel Between the each pairof lugs 8 isswivelly' mounted a screw-eye *9 orthelike, 'adapted when raised to fit in a slot 10 out transverse- 131' in the upper plate 16 from the adjacent edge thereof, outwardly of the flange 7; A

turnable clamping handle member 11 is mounted on the screw, being adapted to hear down on the upper surface of the plate 6 when the latter is lowered-and the screw is in th eslo't as above stated.

For each pair of -lugs Q, lug means is provided on the base plate behind the flange 5, in whiohis swivel ly mounted a screw eye I the intermediate blocks 3 also;

gagettor the adjacent edge In operation, the "clamping screw members are first moved-clear of th e'upper plate, as shown in Fig. :l, so that the upper plate may be swung clear Olltll baseplate. v

*l hefsj tile is then assembled on the base in the manner previously described, and'itlie plate 6 is lowered onto the 'same. Befo-re said plate contacts with the "upper ta ce of the stile, the flange 7 engages the sloping faces of the lugs 8. "The clamping screws 9 are then raised into the slots'lO, and the handles 11 turned down. 1. As soonfias said handles ibear down against the plate,.the latter is moved both downwardly "and later a'll-y', owing to, the I engagementiiott the flange 7 with thelu-gs. Thedownward'pressnre of the plate causes the same to. press zagainst the adjacent portion of the stile, avhile the lateral movement causes the flange *7 to be moved toward the oppositefla'gne '5, pressing the rails of the stile together, and of @colurse evident that the greater the-vertical pressure of the upper plate, the greater willbe the lateral pressure imparted' tothe flange 7.

With the lateral movement of the upper It will shev plate, the swivel hinge members 12, which i are vertically disposed; when the flange [7 first strikes the. lugs. 8,01% even then have .a slight backward tilt, are now caused tobe tilted further backward-or out of a straight line-,1 causing the adjacent portion aQ f the upper plate to be lowered into firm pressing engagement withthe adjacent portion ozt the sti e.

' r it will thus be seen that pressure ris-exerted on all sides :of the stile, which pressure may be easily arranged :to be'substantiaf ly-Lt 1iterm by adjusting the nuts 15 on the hinge members at the outset of operations fi -11 9 The horizontal spacing. between flangesb and 7 when the. platesrt and Gare brought together is such as to (firmly press the 'transverseparts of the stile together. It the stile is lot ,a narrower sizfi afiflitflb spacer -strip may he laid a guuinst the flange WVhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to se cure by Letters Patent is:

1. A clamping device comprising separate and spaced plates, flanges mounted in opposed relation thereon and projecting toward the opposite plates, said plates and flanges being arranged to receive the product to be clamped therebetween, and means for moving the plates and flanges toward each other and into clamping engagement with the opposed faces of the product.

2. A clamping device comprising upper and lower plates, independent of each other, flanges mounted in opposed relation on the plates and projecting toward the opposite plates, a common clamping means, and means whereby when the clamping means is actuated the plates will be moved toward each other and the flanges will similarly be moved toward each other.

3. A clamping device comprising upper and lower plates, independent of each other, flanges mounted in opposed relation on the plates and projecting toward the opposite plates, a common clamping means applied to one plate adjacent one longitudinal edge thereof, and means whereby when the clamping means is actuated said one plate will be moved both laterally and toward the other plate, whereby to cause the flange thereon to be moved horizontally relative tothe opposed flange.

4. A clamping device comprising opposed plates hinged together along one edge, a flange on one plate inwardly of the hinge and projecting toward the other plate, a flange on said other plate projecting toward the first plate and in transversely spaced relation to the flange thereon, means for forcing said plates toward each other, and means on the first plate engaged by the flange on the other plate for causing said flange to be moved toward the opposite flange when the plates are thus forced together.

5. A clamping device comprising opposed plates hinged together along one edge, means applicable to the plates adjacent the edges thereof opposite to the hinge for moving the adjacent portions of the'plates toward a each other, and means whereby at the same time the portions of the plates adjacent the hinge will also and automatically be moved toward each other.

6. Aclamping device comprising opposed plates hinged together along one edge, a flange on one plate inwardly of the hinge and projecting toward the other plate, a flange on said other plate projecting toward the first plate and in transversely spaced relation to the flange thereon, means for forcing said plates toward each other, and lug means on the first plate opposite to the flange thereon, the inner faces of said lugs sloping inwardly from top to bottom, and being positioned to be engaged by the outer face of the flange on the other plate when the latter is moving toward the first plate.

7. A clamping device including opposed plates, means for hinging the same along one edge, such means comprising rigid mem bers projecting substantially at right angles to the plates and extending therebetween, independent swivel connections between said members and both plates, and means for moving the plates together applied thereto along the edges thereof opposite to the hinge means.

8. A clamping device including opposed plates, means for hinging the same along one edge, such means comprising rigid members projecting substantially at right angles to the plates and extending therebetween, independent swivel connections' between said members and both plates, means for moving the plates together applied thereto along the edges thereof opposite to the hinge means, and means for adj ust-ing the operative length between said swivel connections at will.

In testimony whereof I afliX my signature.
